Application June 24,

4 Claims.

' My invention relates to collar and cuff starching machines having a bottom feed roll in combination-,witha plurality of top press rolls in arcuate arrangement with said bottom feed roll and adapted to starch collars and/or cuffs without starching the shirt body and to carry out the starching operation in a more efiicient manner.

The object of my invention is to save time and material and to improve the quality ofv the work turned out.

My objectives are obtained thru the use or" the machine illustrated in the accompanying drawings and minutely described in the specification. I

Throughout the drawings and the specification similar numerals refer to similar parts. 7

Fig. 1 of the drawings is a plan view with the upper press rolls removed; Fig. 2 is a vertical section on the line 2-2 of Fig. 1; Fig. 3 is a vertical section on the line 3-3 of Fig. 1; Fig. 4 is an enlarged section on the line 4--4 of Fig. 3.

Prior to the war when labor was not such an item, collars and cuffs were dipped in the starch and wrung out by hand. Since labor became scarce and costly the starch is put in an ordinary washing machine and the entire shirt agitated therein. The average customer does not want an all starched shirt. The laundry operator must look to the cost of labor and material and to the satisfaction of the customer if he is to stay in business.

Quality in starch work means the elimination of high or bright spots or streaks. These are caused by an excess of starch which burnishes during ironing and causes high-lighted spots or streaks on the collars or cuffs.

Several attempts have been made to provide a machine which would distribute the starch thruout a collar or cuff in a satisfactory manner without getting it into the body of the shirt. In each instance a combination of two rolls one above the other was used. These arrangements have not proved satisfactory.

I discovered that by using a plurality of press rolls I could distribute the starch more evenly throughout the collar or cuff and leave the same in better condition for ironing. The arrangement of these rolls will now be described in conjunction with the complete machine.

The base I of the machine is made hollow for the reception of the starch pan 2 to which is attached the heating element 3 provided with an aquastat 4 which extends into the liquid starch 5 in the pan 2 so that the aquastat may control upper end of the the operation of the switch (not shown) thru which electricity flows to the heating element 3 thus permitting the starch to be kept at the desired temperature. If cold starch is used the heating element, aquastat, and switch, may be dispensed with.

In the top of the base! is mounted a roll 6 to which is secured a relatively firm rubber cover I.

This roll 5 is journalled in the bearings 8 in the base I and extends into the starch 5 so that the same may be raised out of the pan during the revolution of the roll. The roll 6 is revolved thru the agencypf the motor 9 and the reduction gear 10 which is connected to the roll shaft l l by the flexible coupling l2. The reduction gear. is mounted on the bracket 13 formed on the side of the base I. i I find that a roll 12" in diameter operated at about-10 R. P. M. to be very satisfactory. It is to be seen that the speed reduction may be had thru a system of pulleys and that another prime mover may motor.

The base I is provided with the hinge lugs M for the reception of the hinge pins [5 which engage the lugs l6 formed on the top l1 whose top surface l8 forms the support for the work being passed between the lower roll 6 and the upper press rolls I9, 20, 2|, 22, and 23. The use of five rolls has been found to be very satisfactory. However, no limitation as to this number is to be construed. Each of the above press rolls is rotatably mounted in its respective bearing carriers ISA, 20A, 2lA, 22A, and 23A, which are slidable in their respective guideways I93, 203.

2IB, 22B, and 233. These guideways are shown formed as part of the arms 24 which are cantilevered out from the base 25 secured to the top 11 by the cap screws 26. When the press rolls 19 to 23, inclusive, are cantilevered out over the bottom roll 6, the arrangement may be termed open-ended. The open end is designated by the letter A. This open-ended arrangement permits the collars and cufis only of a shirt to be passed between theupper and lower rolls.

The upper press rolls I9 to 23 are spaced in arcuate'arrangement with respect to the curve.- ture of the lower roll 6 and each is in frictional contact with and driven by the lower roll. The frictional contact of each roll l9 to 23, inclusive, is regulated by the tension in springs as illustrated in 2IC, Fig. 4. The spring tension in turn is regulated by the plugs 21 threaded into the guideways 193 to 233. The plugs 21 engage the upper end of the springs whose opposite end engages the be used in lieu of the bottom of the g caught between the trolls too.

a with {the press rolls 1!! to 23 springpocket 28 formed in the upper end of the bearing carriers ISA to 23A, inclusive.

In practice I regulate the tension in'the springs v for roll l9 so that the collar or cufi will just be serve to smooth out wrinkles so that when the collar or cufl" is passed between the rolls it comes out in a smooth condition and with the high spots removed. The rolls I9 to 23 have .been made M a firm rubber composition similar to wringer rolls 1 used in the trade and have proven very satisfactory.

Mention has heretofore been made .ef the hinged top IT. This top I1 has been hinged to permit it to be thrown back so that the "lower roll Mi may-be cleaned or removed. When the top H :is thrown back the press rolls 1-1 9 1:023 may-be cleaned or removed. It i also evident that when feeding work between the rolls fingers may Joe Should this mail pen the operator may cause the top .I-I together to be lifted away from the lower roll 6. This is :brei ghtabout by the operation of the lever 29 which is pivotably secured to the top I 1 and provided with a portion 30 adapted to engage the bottom -face of ,the ,rib 31, of the base I whereby the top. a! 1 is neleasably securedtorthe base 4,. When the top 1|?! has been released from the base @I it is lift d by the compression spring 32 interposed between the two sections. Y

,I-tisvery evidentthat-many deviations may be made in the design and arrangement of ,ipargts in idea and therefore I do not limit my invention to the exact form shown and described but extend it to all that comes fairly within the scope of the appended claims.

I claim:

2. A collar and buff stare-hing machine having a driven bottom starch-carrying roll, a plurality of top press rolls cantilevered over and arranged in arcuate relation to the bottom roll and in frictional contact therewith, and means for varying the frictional contact of the press rolls with the bottom roll.
